I need good hearing protection.

Cal, I feel compelled to add this, especially after your last post. As a condition my employment, I MUST conform to my employers requirements that I wear plugs under muffs. The equipment that I use makes so much noise that either plugs or muffs alone will not reduce the noise to below allowable federal standards. I wear the form fitted plugs under Pelter muffs. Just to help others understand, I run a Dry Ice Blaster. The principal is about the same as a bead blaster, with the exception that I use dry ice pellets under pressure to clean things. A 1"air line charged with about 96 psi makes a bunch of noise. Can you say instant head pain? All this noise happens at arms length. Plugs under muffs work. Can you read lips?
